Got a new intercooler and fitted it yesterday, Got two Spal fans with it, where is the best place to put each fan and how do you put the other fan on a new relay? any help would be appreciated

 

i'd putr the fans as far right to the rad as possible, dunno how to wire it up to another relay tho?

 

mount the fans on the rad, between cooler and rad then just splice the 2 fans together and connect to original wiring, and make sure they suck not blow (oooh errr )

put a plastic bag over the front to check

 

I wouldnt advise this. The fans draw a lot of current and to put 2 fans in the circuit will draw twice as much on the same wiring At best you will find the fans run slower because of the wires cant feed them enough current. At worst the wires will get so hot the whole car will catch fire.

Use the feed to the standard fan as a relay trigger to drive the second fan. Take the power feed for the relay directly (or as near as possible) from the battery (fused of course!).

 

thats what it said to do on the instuctions of the IC for our RST and its been fine

dont think the car has really been used since fitting tho

 

Scary instructions! do they draw less current than the standard fan then?

 

either way i think id rather be save and use a relay, plull it will spin faster with a seperate power supply correct?, it hasnt overheated at all with the one fan on the rad sucking! in fact it doesnt even reah the M on the temp guage!!!!

cheers guys

 

There will be less resistance in the wiring when using the relay because

a) the wiring is newer - old wiring gets brittle and increases resistance
b) you are taking a direct feed from the battery (via a relay) so you are not going through the whole car loom to power the fan (longer wiring also increases resistance)

so yes it will be fed more current so spin faster

 

thanks ile get it all sorted tomoz just gota get the new engine in next!!! should be fun!
